Arthrology of the Forelimb Flashcards
Collateral ligaments of the shoulder joint
The tendons of insertion of M. infraspinatus, M. supraspinatus and M. subscapularis
Lig glenohumerale laterale/mediale
Ligaments of the shoulder joint. Poorly developed thickenings of the fibrous part of the joint capsule
Transverse humeral ligament
Ligament of the shoulder joint. A collagenous thickening across the tendon of origin of m. biceps brachii at the intertubercular groove
The articulations of the Elbow joint
Humeroradial joint (Humeral capitulum and trochlea with head of Radius); Humeroulnar joint (Humeral trochlea with incisura trochlearis on the Ulna); Proximal Radioulnar joint (Circumferentia articularis radii with Incisura radialis on the Ulna)
Ligament collaterale cubiti lateraleqmediale
Ligaments of the elbow joint. Pronounced thickenings in the fibrous layer of the capsule. The beceps’ and brachialis’ tendons cover the distal portion of the medial collateral ligament
Ligament anulare radii
Ligament of the elbow joint. A thin band that runs transversely around the radius. It attaches to the lateral and medial coronoid processes of the Ulna. Lies deep to the collateral ligament
Ligament olecrani
Ligament of the elbow joint. An elastic ligament thet passes between the craniomedial aspect of the olecranon to the medial border of the olecrenon fossa
Ligament interosseum antebrachii
Ligament of the elbow joint. A condensation of collagenous tissue that units the radius and ulna proximally
Membrana interossea antebrachii
The dense membrane that connects the interosseus margins of the Radius and Ulna, forming the Radioulnar syndesmosis. It also separates between the exensor and flexor compartments of the forearm
Articulatio radioulnaris distalis
The distal radioulnar joint is formed between the circumferenca articularis ulnare and the incisura ulnaris of the Radius. Incorporated into the antebrachiocarpal joint.
Ligament radioulnare
Ligament of the distal radioulnar joint. This is a short lig. which tightly connects the cranial surfaces of the distal Radius and Ulna
Artriculations of the carpal joint
Antebrachiocarpal joint - most proximal, lies between the distal radius and ulna and the proximal row of carpal bones. Includes the distal radioulnar joint and the articulations of the accessory carpal bones; Middle carpal joint - lies between the proximal and distal rows of carpal bones; Carpometacarpal joint - most distal, lies between the distal row of carpal bones and the bases of the metacarpal bones. Includes the articulations between the bases of adjecent metacarpal bones
Fibrous joint
Without joint space; Little or no mobility
Cartilaginous joint
Without a joint space; limited mobility (streching, etc.)
Synovial joint
With a joint space; greater mobility
Synarthrosis
Another name for fibrous joint
